JOHN: GOOD EVENING.

I'M JOHN YANG.

TONIGHT, TWO COMMUNITIES HALF A WORLD APART ARE STRUGGLING WITH THE AFTERMATH OF A MASS SHOOTING.

IN SYDNEY, TWO GUNMEN KILLED AT LEAST 15 PEOPLE CELEBRATING HANUKKAH ON AUSTRALIA'S MOST FAMOUS BEACH.

AUTHORITIES CALL IT A TERRORIST ATTACK ON JEWISH AUSTRALIANS.

AND WE BEGIN IN PROVIDENCE, RHODE ISLAND, WHERE TWO BROWN UNIVERSITY STUDENTS WERE KILLED AND NINE OTHERS WOUNDED WHEN A MAN OPENED FIRE IN A CLASSROOM WHERE A REVIEW SESSION FOR AN ECONOMICS EXAM GOING ON.

AUTHORITIES SAY A PERSON OF INTEREST -- DESCRIBED AS A MAN IN HIS 20'S -- WAS TAKEN INTO CUSTODY AT A HOTEL ABOUT 20 MILES FROM PROVIDENCE.

TODAY POLICE PATROLLED THE STREETS AROUND THE BROWN NIVERSITY CAMPUS AS SNOW FELL, A STARK CONTRAST TO LAST NIGHT, WHEN POLICE RESPONDED IN FORCE TO REPORTS OF AN ACTIVE SHOOTER.

THEY SEARCHED THE CAMPUS FOR A SUSPECT.

STUDENTS WERE TOLD TO SHELTER IN PLACE.

FOR SOME THAT MEANT A CLASSROOM OTHERS WERE ESCORTED TO AN , ATHLETIC CENTER.

ENGINEERING STUDENT CHIANGHENG CHIEN WAS WORKING IN A LAB WHEN THE ALERT WENT OUT.

>> WE DECIDED TO CLOSE ALL THE DOORS AND TURN ALSO THE LIGHTS OFF AND HIDE UNDER THE DESKS AND WAIT FOR THE NEXT NOTIFICATION.

JOHN: ANOTHER WITNESS DESCRIBED THE SCENE LAST NIGHT.

>> SOMEONE WAS GETTING CPR.

I SEEN A FEW PEOPLE GETTING CARRIED ON STRETCHERS.

JOHN: VIDEO FROM SURVILLANCE CAMERAS SHOW A FIGURE COMING OUT OF THE BUILDING WHERE THE SHOOTING TOOK PLACE.

POLICE WON'T SAY IF IT LED THEM TO THE MAN THEY TOOK INTO CUSTODY.

THIS MORNING, PROVIDENCE MAYOR BRETT SMILEY REFLECTED ON THIS DIFFICULT TIME.

>> WE KNEW IT COULD HAPPEN ANYWHERE, INCLUDING HERE, BUT THAT'S NOT THE SAME AS IT HAPPENING IN OUR COMMUNITY.

AND SO, THIS IS AN INCREDIBLY UPSETTING AND EMOTIONAL TIME FOR PROVIDENCE, FOR BROWN, FOR ALL OF US.

JOHN: SCHOOL OFFICIALS HAVE CANCELLED CLASSES AND EXAMS FOR THE REST OF THE YEAR.

MANY STUDENTS WILL HEAD HOME FOR THE HOLIDAYS.

WHAT SHOULD BE A JOYOUS TIME, NOW SHATTERED BY THE TRAGIC CYCLE OF GUN VIOLENCE.

IT'S A SAD SIGN OF THE TIMES THAT THIS WAS NOT A NEW EXPERIENCE FOR AT LEAST TWO BROWN STUDENTS -- THEY HAD BEEN THROUGH SHOOTINGS AT THEIR HIGH SCHOOLS.

IAN DONNIS IS A REPORTER AT OCEAN STATE MEDIA, RHODE ISLAND'S PBS AND NPR STATIONS.

IS THERE ANYTHING NEW ON THE INVESTIGATION?

IAN: THE MOST SIGNIFICANT DEVELOPMENT, EARLY SUNDAY LAW ENFORCEMENT TOOK INTO CUSTODY A PERSON OF INTEREST AT A HOTEL IN COVENTRY ABOUT 20 FIVE MILES SOUTHWEST FROM PROVIDENCE.

OFFICIALS HAVE BEEN GUARDED IN RELEASING INFORMATION ABOUT THE SUSPECTS.

THEY SAY THEY DON'T WANT TO COMPROMISE THE INFORMATION.

ONE OF THE FEW THINGS WE KNOW, HE IS A MAN IN HIS 20'S.

THE FBI DIRECTOR KASH PATEL ON X TWEETED THAT THE FBI HELPED TO LOCATE THE PERSON THROUGH CELL PHONE TRACKING AND A TIP FROM PROVIDENCE POLICE, BUT THE PROVIDENCE AUTHORITIES HAVE BEEN VERY GUARDING AND SAYING -- GUARDED IN SAYING ANYTHING BEYOND THAT.

JOHN: IS THERE SPECULATION ABOUT THE BUILDING HE CHOSE FOR THIS ATTACK?

IAN: IT RAISES A LOT OF QUESTIONS.

THE PLACE WHERE THE SHOOTING TOOK PLACE IS AN ENGINEERING AND PHYSICS BUILDING WHERE AN EXAM WAS BEING GIVEN.

THAT IS A VERY SPECIFIC LOCATION.

IF A MASS SHOOTING WANTED TO CREATE THE MOST CARNAGE, THAT IS PROBABLY NOT THE PLACE THEY WOULD GO.

OFFICIALS HAVE NOT SAID WHETHER THE PERSON OF INTEREST PRIOR CONNECTION WITH BROWN UNIVERSITY.

THAT IS AN OBVIOUS QUESTION TO FOLLOW.

THEY HAVE NOT CITED ANYTHING AS FAR AS MOTIVE.

JOHN: WHAT DO WE KNOW ABOUT THE STATUS OF THE STUDENTS WHO WERE WOUNDED?

IAN: THERE IS BETTER NEWS ABOUT THAT.

TODAY OFFICIALS SAY THAT SEVEN OF THE NINE INJURED ARE NOW IN STABLE CONDITION.

THAT IS IMPROVEMENT FROM SATURDAY WHEN THEY WERE CRITICAL.

ONE PERSON IS STILL CRITICAL BUT STABLE.

ONE OF THE INJURED HAS BEEN DISCHARGED FROM THE HOSPITAL.

JOHN: AT THE BRIEFING I KNOW THE OPERATIVE REASON WHY THE NAMES OF THE TWO VICTIMS HAVE NOT BEEN RELEASED.

IAN: THE MAYOR OF PROVIDENCE SAID NOT UNTIL ALL FAMILIES HAD BEEN NOTIFIED, THAT WAS THE EXPLANATION FOR WHY THEY HAVE NOT BEEN IDENTIFIED, THE TWO STUDENTS WHO WERE KILLED, AND THE OTHERS INJURED.

JOHN: HE SAID AT LEAST ONE OF THE FAMILIES WAS TRAVELING SO THEY WERE DIFFICULT TO REACH.

WHAT IS THE SITUATION ON CAMPUS RIGHT NOW?

IAN: THIS TAKES PLACE IN RHODE ISLAND, A SMALL STATE IN THE NATION WHERE WE ARE ALL CLOSELY CONNECTED WITH ONE ANOTHER.

THERE WAS CLEARLY A LOT OF ANXIETY AND CONCERN WHEN THE SHOOTER WAS CONSIDERED STILL AT LARGE YESTERDAY.

OFFICIALS PUT A SHELTER-IN-PLACE ORDER IN EFFECT AND THAT WAS LIFTED AFTER THE PERSON WAS APPREHENDED TODAY.

I THINK THERE IS A LOT OF SADNESS.

CERTAINLY RHODE ISLAND HAS EXPERIENCED GUN VIOLENCE IN TERMS OF CRIME AND EVEN SHOOTOUTS BUT THERE HAS NEVER BEEN A MASS SHOOTING OF THIS TYPE AND A LOT OF SADNESS.

THE BROWN UNIVERSITY PRESIDENT CHRISTINA PAXTON SAID THE CAMPUS IS REELING, AND IT WILL TAKE A LONG TIME FOR PEOPLE TO COPE WITH THIS.

STATE AND CITY OFFICIALS MADE COUNSELING RESOURCES TO ASSIST IN THAT EFFORT, BUT IT IS DIFFICULT.

JOHN: AT BROWN IS THERE ANY DISCUSSION OR CONCERN ABOUT HOW EASILY THIS SUSPECT WAS ABLE TO ENTER A CLASSROOM BUILDING?

IAN: INDICATIONS WERE THAT ACCESS WAS EASIER TO THIS BUILDING BECAUSE EXAMS WERE BEING GIVEN.

UNIVERSITY OFFICIALS SAID WHEN EXAMS ARE GIVEN LIKE THAT, THE OUTSIDE DOORS TO BUILDINGS ARE OPEN.

THEY EXPLAINED THAT USUALLY SOMEONE HAS TO CHECK IN IN THE EVENING.

BUT THERE ARE A LOT OF POROUS PLACES IN AN OPEN SOCIETY.

HOW TO STOP SOMETHING LIKE THIS AGAINST A PERSON INTENT ON COMMITTING VIOLENCE IS A TOUGH QUESTION TO RESOLVE.

JOHN: IAN DONNIS OF OCEAN STATE MEDIA AND RHODE ISLAND, THANK YOU.

LATE WORD SINCE WE SPOKE WITH IAN.

AUTHORITIES IDENTIFY THE PERSON OF INTEREST AS 24-YEAR-OLD BENJAMIN ERICKSON.

THERE ARE NO OTHER DETAILS.
